In Australia, droughts and dry spells are common, so storing water is essential. That’s why many homeowners and businesses are investing in water tanks to capture and store rainwater. Whether you need a small tank for your garden or a large tank for your household supply, there are plenty of options available.
In this guide, we’ll cover everything you need to know about rainwater tanks, poly tanks, plastic tanks, and more. We’ll also look at one of the country’s most trusted suppliers, The Tank Factory, and why Australians choose them for reliable and affordable water storage solutions.
Why Invest in a Water Tank?
Water is one of our most valuable resources. A rainwater tank helps you:
- Save money on bills by using captured rainwater for toilets, laundry, or gardens, which reduces reliance on mains water.
- Support sustainability by harvesting water. This eases demand on municipal supplies and cuts down on stormwater runoff.
- Prepare for droughts. Having a dependable water tank gives you peace of mind during dry spells.
For many Australians, getting a rainwater tank is both a financial and environmental benefit.
Different Types of Water Tanks
Not all water tanks are alike. Here are the main types you’ll find when searching for the right solution.
1. Poly Water Tanks (Polyethylene Tanks)
Poly tanks are the most popular choice today. Made from tough polyethylene, these tanks are lightweight, affordable, and built to endure harsh Australian conditions.
Benefits of poly tanks include:
- UV protection for hot summers.
- Rust-proof and resistant to corrosion.
- Available in various sizes and colors.
If you want something low-maintenance and long-lasting, a poly tank is often the best option.
2. Steel Water Tanks
Steel tanks are known for their strength and classic look. They work well for very large storage needs, but they can be more expensive than plastic tanks and require a protective liner.
3. Concrete Water Tanks
Concrete tanks are sturdy but heavy. They’re often installed underground, which is ideal for sites with limited space.
4. Slimline Water Tanks
Perfect for urban areas, slimline tanks fit neatly along walls or fences. These are typically made from polyethylene, providing the benefits of a plastic tank while conserving space.
Why Poly Tanks Are So Popular
When comparing tank types, poly water tanks are often the top choice for many households. Here are the reasons:
- Durability – Poly tanks do not rust, crack, or corrode easily.
- Affordability – Generally cheaper than steel or concrete tanks.
- Flexibility – Available in round, slimline, or custom shapes.
- Color options – You can match your poly tank with your roof, fence, or garden design.
It’s no surprise that across Australia, poly tanks are the go-to option for families needing reliable water storage.
Plastic Tanks vs. Other Materials
The term plastic tank usually means polyethylene tanks. Some people have concerns about safety, but high-quality plastic tanks in Australia are made from food-grade, BPA-free materials. This ensures that your stored rainwater is safe for household use.
Compared to steel or concrete, a plastic tank is:
- Easier to transport.
- Simpler to install.
- Resistant to cracking from temperature changes.
That’s why plastic tanks are predominant in the residential market.
Choosing the Right Size Water Tank
Before buying a rainwater tank, consider:
- Roof size – Larger roofs catch more water.
- Rainfall patterns – Look up local averages for your area.
- Usage – Do you just want water for the garden or for your entire home?
Sizes range from small 500L poly tanks for backyard use to massive 50,000L rainwater tanks for farms and businesses.

How to Install a Water Tank

Steps include:
- Site preparation – Ensure you have a flat, stable base, often a concrete slab or compacted sand.
- Plumbing setup – Connect downpipes, filters, and diverters for clean water.
- Tank installation – Carefully position and secure your poly or plastic tank.
- Pump system (optional) – If using rainwater inside the house, you’ll need a pump.
- Many homeowners opt for professional installation, but DIY is possible for smaller tanks.
Maintenance Tips for Longevity
- A good water tank can last decades with proper maintenance. Here’s how:
- Clean gutters regularly to prevent debris from entering the tank.
- Check for leaks or damage in pipes and fittings.
- Install a first-flush diverter to keep water cleaner.
- Flush and inspect your poly tank every couple of years.
Environmental Benefits of Rainwater Tanks

With climate change causing more extreme weather, having your rainwater tanks makes you less vulnerable to water restrictions and shortages.
